Aegis Group may be in talks to sell off some of its biggest assets, but it's also bulking up on digital advertising services, announcing a deal this morning to acquire Japan's Filefix, and integrate it into its Isobar network of digital agencies.

Terms of the agreement were not disclosed, but Aegis said Filefix was founded in 2007 and has grown rapidly based on its expertise in mobile and cross-platform integration. It said Filefix has gross assets of about $1.27 million.

Filefix roster includes Japan Airlines, Panasonic and Casio.

The deal comes as Aegis is in exclusive negotiations to sell its Synovate marketing and media research division to Paris-based Ipsos, a deal some speculate may be a prelude to the rest of Aegis - including media services networks such as Isobar, Carat, Posterscope and Vizeum - going into play.
